“The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) has informed Chad Mendes of a potential Anti-Doping Policy violation stemming from an out-of-competition sample collection.

USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case. It is important to note that, under the UFC Anti-Doping Policy, there is a full and fair review process that is afforded to all athletes before any sanctions are imposed. Additional information will be provided at the appropriate time as the process moves forward.”

Mendes (17-4) hasn’t been booked for a fight, since he was taken out by Frankie Edgar in December. That defeat was the Team Alpha Male fighter’s second stoppage loss in a row, as Mendes was finished by Conor McGregor in July.

The 31 year-old Mendes is currently ranked #4 in the UFC’s 145 division.
